305-048-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-258 is a standard card edge connector from the 305 series, designed for dual-edge board mating. It features 48 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The contacts are constructed from copper alloy with gold plating to ensure reliable conductivity, rated for 5 A current. This header utilizes a solder pin termination style and is intended for panel mount installation at a vertical angle.

• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compatibility with required PCB thickness and termination style. Ensure that the selected variant matches the necessary environmental ratings and current specifications for the target application before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with a 3.96 mm pitch is required for vertical panel mounting. The dual-edge configuration is suitable for applications requiring access to both sides of the circuit board. Verify that the host system's mechanical constraints align with the specified 1.57 mm maximum board thickness.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series provides various position counts and termination options to support diverse interface requirements across industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on similar pitch or position counts without confirming mechanical and electrical parameter alignment.
